Q5.
e) 125 ÷ 15
Answer
Take away groups of 15 again and again.
15 × 8 = 120
125 − 120 = 5
Groups taken = 8
Left over = 5
125 − 120 = 5
Groups taken = 8
Left over = 5
125 ÷ 15 = 8, remainder 5
Check: 15 × 8 + 5 = 125 ✓
Q6.
f) 94 ÷ 11
Answer
Take away groups of 11 again and again.
11 × 8 = 88
94 − 88 = 6
Groups taken = 8
Left over = 6
94 − 88 = 6
Groups taken = 8
Left over = 6
94 ÷ 11 = 8, remainder 6
Check: 11 × 8 + 6 = 94 ✓
Q7.
g) 440 ÷ 22
Answer
Take away groups of 22 again and again.
22 × 20 = 440
440 − 440 = 0
Groups taken = 20
Left over = 0
440 − 440 = 0
Groups taken = 20
Left over = 0
440 ÷ 22 = 20, remainder 0
The remainder is 0, so 22 divides 440 exactly.
Q8.
h) 508 ÷ 18
Answer
Take away groups of 18 again and again.
18 × 20 = 360
508 − 360 = 148
18 × 8 = 144
148 − 144 = 4
Groups taken = 20 + 8 = 28
Left over = 4
508 − 360 = 148
18 × 8 = 144
148 − 144 = 4
Groups taken = 20 + 8 = 28
Left over = 4
508 ÷ 18 = 28, remainder 4
Check: 18 × 28 + 4 = 508 ✓
